DuPont Introduces New Diacetyl-Fighting Enzyme

BRABRAND, Denmark — DuPont will present a new brewing enzyme for faster production of consistently tasty beer at BrauBeviale in Nuremburg, Germany, Nov. 10th to12th.

DuPont™ Danisco® Alphalase® Advance 4000 is a robust solution for brewers to reduce or completely eliminate diacetyl during beer fermentation. The enzyme keeps beer quality high while optimizing production capacity and saving on energy consumption.

Tackling a buttery off-flavor

A well-known organic compound also present in butter, diacetyl develops naturally during beer fermentation. Its butterscotch flavor, however, is generally considered undesirable – creating a need to keep diacetyl levels low in the final beer.

Brewers typically achieve this by extending the beer maturation period. This ensures the diacetyl is broken down into flavor-neutral compounds once secondary fermentation is complete.

DuPont™ Danisco® Alphalase® Advance 4000 solves the issue by preventing the generation of diacetyl during fermentation. With a diacetyl level that is safely below the accepted flavor threshold, brewers can shorten the maturation period considerably, obtaining a uniform maturation, optimizing production throughput and cutting down on the energy consumed in the process.

“Extensive tests have shown that Alphalase® Advance 4000 is efficient across a broad spectrum of brewing protocols and adjuncts ranging from corn and rice to sorghum and cassava,” says Iliana Yanez.

“Importantly, Alphalase® Advance 4000 ensures reliable diacetyl control without side effects. The essential properties of the final beer are unchanged,” Yanez added.
